Melting Icebergs

I need some help from you guys here at chess.com. I'm currently thinking about purchasing Modern Chess Openings, 15th Edition. However, I recently read some reviews saying that it wasn't as great as it advertises itself to be. What do you guys think? Is it worth the money or is it a waste of time?

Oh, and I found this neat little game and I thought you guys might like to check it out. It's quite interesting, as Caruana throws sacrifice after sacrifice at his opponent, who still seems to be hanging on! But eventually, things clear up. By the way, I borrowed the title from chessgames.com.
